Calculator

In JHS, SHS, BECE and WASSCE, the side tab on the left edge has a Calculator. It is not there for pre-school or primary classes, where sums are done in the head and on paper.

It opens over the page, so the lesson keeps its place. The arrow at the top moves it to the top or bottom of the screen; the cross closes it.

Basic and Scientific

Basic: the four operations, brackets, % (15% × 200 is 30; 200 + 15% is 230), ±, CE (clears the last number), AC (clears everything) and Ans (the last answer).
Scientific adds sin, cos and tan (DEG or RAD), powers and roots, log and ln, π and e, x!, 1/x, |x|, EXP for powers of ten, mod for the remainder, and the memory keys MC, MR, M+ and M−.
2nd changes the keys to sin⁻¹, cos⁻¹, tan⁻¹, x³, ∛, 10ˣ and eˣ. a/b shows the answer as a fraction when it is one.

History and the BECE exam

The clock button shows your recent sums; tap one to use it again. On a computer you can type the sum and press Enter.

Calculators are not allowed in the BECE, so the calculator is off while a BECE paper is sat as a timed exam. It works in Practice, and in WASSCE papers.
